Question

/*Use recursion in the function: void getDigit( int num)

/* Try this program and implement the function void getDigit( intnum) so that it displays the digits in a given number. For example, the number, 1234 consist of 1, 2, 3 and 4.

This is an exercise to demonstate the use of a recursive function and the use of recusrion in C++
